Abstract

A folding mechanism of a treadmill having a slide pusher at the bottom of a platform frame thereof. By use of a pneumatic cylinder, the platform frame may push the rear support in an opposing direction to keep a ground-touching slide action when the platform frame is moved upward and downward. In this way, an effective, strong, and auxiliary support force is created until the platform frame is moved in a vertical storage position or in a horizontal operation position.

Claims

1. A folding mechanism of a treadmill having a platform frame with a transmission motor at one side thereof for driving a continuous moving belt into rotation by use of a transmission belt, a front roller, and a rear roller, a lifting motor being employed to move an adjusting support upward and downward for adjusting the supporting angle of the platform frame, two connection pins being disposed at both sides of the platform frame, respectively, for pivotally coupling a handrail assembly and a rear support, respectively,

wherein a slide rail, on which a slipper moves, is interposed between a first and a second strengthening bar;

wherein a slide pusher is pivotally attached to the bottom of the slipper while the other end of the slide pusher is pivotally connected to the rear support; and

wherein a pneumatic cylinder is pivotally coupled to the bottom of a third strengthening bar of the platform frame while the other end of the pneumatic cylinder is pivotally attached to a central crossbar of the slide pusher.

2. A folding mechanism of a treadmill having a platform frame with a transmission motor at one side thereof for driving a continuous moving belt into rotation by use of a transmission belt, a front roller, and a rear roller, a lifting motor being employed to move an adjusting support upward and downward for adjusting the supporting angle of the platform frame, two connection pins being disposed at both sides of the platform frame, respectively, for pivotally coupling a handrail assembly and a rear support, respectively,

wherein a slide rail, on which a slipper moves, is interposed between a first and a second strengthening bar;

wherein a slide pusher is pivotally attached to the bottom of the slipper while the other end of the slide pusher is pivotally connected to the rear support; and

wherein a pneumatic cylinder is pivotally coupled to the bottom of a third strengthening bar of the platform frame while the other end of the pneumatic cylinder is pivotally attached to the rear end of the slide pusher.
